As you are aware, this is ChatGPT finding and repeating proposals made by people, rather like that person in a meeting who repeats ideas that others have just proposed as if they were their own, so it is not an example of an AI improving itself, and would not be so even if it were able to implement those suggestions itself - the improved version would still be doing the same thing. (Furthermore, note that some of these suggestions, particularly 3, are goals rather than solutions.) Requiring AIs themselves to innovate in the field of AI would be a stringent test - probably too stringent as a definition of AI, though equally one that would leave little room for doubt that it had been achieved - and all this discussion shows is that TacticalCoder's outline of a test was not sufficiently guarded with caveats to avoid being open to misinterpretation.
